Article Summary

We've seen a number of unusual speakers before, such as the Whamodyne glass speakers or Solid Acoustics' dodecahedron speakers, but concrete speakers are definitely something new. It's definitely not a very popular material for audio systems, but Israeli designer Shmuel Linski would like to change that with his "Exposed" concrete speakers, each of which weighs 123 pounds (56 kg). They're just one part of his line of unusual creations, that include a concrete coffee maker and a concrete canoe.
